I would like to have a signature fragrance, but there are so many I like, I couldn't possibly pick just one. I guess all my favorites probably fall into one "fragrance family", but as with my makeup, I love variety.
i actually never really worn perfume until this year at christmas time when i got some perfumes. i couldn't find one i really liked, and if i did they were too expensive! i got britney spears fantasy which i love (not britney herself though lol) and i got puma woman (i think it's called) so in that case i don't switch often lol.
I love to switch them depending on the mood and day, although I do have longer phases when I use only one scent that I am obsessed with at the moment. Right now it is Sensual Amber from Bath and Body Works
